Collisional depolarization of Zeeman coherences in the 133 Cs 6 p 2 P 3 / 2 level : Double - resonance two - photon polarization spectroscopy
نویسندگان
چکیده
An experimental investigation of the Cs 6s S1/2→6p P3/2→10s S1/2 double-resonance two-photon polarization spectrum has been made. In the investigation, a linear polarization degree was measured to extract the alignment depolarization cross section in the cesium 6p P3/2 level due to collisions between ground-level argon and excited 6p P3/2 cesium atoms over the Zeeman coherences. The spectra show strong depolarization of the Cs 6p P3/2 level. The measured alignment depolarization cross section value of 186 58 Å 2 is in good agreement with the experiment and theoretical predictions.

We have experimentally investigated the anisotropy-dependent circular polarization spectra of the Cs 6sS1/2→6p P3/2→10s S1/2 double-resonance transition in the presence of Ar. Satisfaction of doubleresonance condition, achieved by use of a two-photon two-color pulse laser excitation scheme, was monitored by measurement of the intensity of the 9pP1/2→6s S1/2 cascade fluorescence at 361.73 nm.

A precision polarimeter has been developed to measure the linear polarization degree of Rayleigh scattered light. Application is made to measurement of the linear depolarization spectrum of atomic Cs in the vicinity of the 6s S1/2→6p P j resonance transition. For measurements in an ;220 cm range around the 6s S1/2→6p P3/2 resonance transition, the ratio of line strengths for the two resonance t...

We have measured the cross section for the disorientation of excited 6pP1/2 Cs atoms by collisions with ground state Ar atoms by optical–optical double resonance circular polarization spectroscopy. Circular polarization spectra were measured for the 6sS1/2 6pP1/210s S1/2 transition. Orientation was optically induced in the P1/2 state by circularly polarized light. A polarization degree was meas...

— The only way to obtain reliable empirical information on the intensity and topology of the weak magnetic fields of the “quiet” solar chromosphere is via the measurement and rigorous physical interpretation of polarization signals in chromospheric spectral lines. The observed Stokes profiles reported here are due to the Hanle and Zeeman effects operating in a weakly magnetized plasma that is i...
